Crucial P310 2TB M.2 NVMe SSD CT2000P310SSD8 review

The P310 2TB is a PCIe 4.0 x4, NVMe 2.0 drive in the M.2 2280 form factor. Tom's Hardware lists it as single-sided. Inside is a Phison E27T controller with no DRAM, which uses system memory instead, paired with Micron's 232-layer QLC flash. That combination sets out what the drive does well and where it falls short.

Crucial's datasheet rates the 2TB model at 7,100 MB/s sequential read and 6,000 MB/s sequential write. For random work, the datasheet gives 1.2M IOPS for both read and write. Tom's Hardware lists 1,000K read and 1,200K write, so the sources disagree on random read.

Those are rated peaks, though. Owners of other P310 variants report that sustained writes slow down once the cache fills or the drive heats up. Those reports cover the 2230 version and a 1TB 2280 model, not this 2TB 2280 drive. Crucial doesn't list a sustained write speed. With a DRAM-less controller and QLC flash, plan around the rated numbers for bursty desktop loads rather than long, continuous writes.

This is the weak point. The 2TB P310 is rated at 440 TBW. That works out to about 220 TB written per terabyte of capacity, or roughly 0.12 drive writes per day. The figure doesn't appear in Crucial's own datasheet; it comes from third-party sources.

The warranty runs for five years or until the drive reaches its TBW limit, whichever comes first. With a 440 TBW ceiling, heavy writers could hit the limit before the five years are up. Logging, VM disks, constant downloads and video scratch work would all wear it faster. For a games or OS drive that is mostly read, the five-year term is likely to be the limit that applies.

Owner comments reflect this split. Some readers on one review page called the endurance too low for the price and the QLC flash overpriced. Another replied that 220 TBW is enough for most people. That evidence comes from a single page's comments, so treat it as a sentiment rather than a consensus.

Crucial publishes little here. Its only power claim is a performance-to-power ratio up to 40% better than the earlier P3 Plus. The sources read give no wattage figures for active, idle or low-power states. They also don't mention a heatsink version of the drive.

Owners of other P310 variants link some write slowdowns to the drive heating up. If your board has an M.2 heatsink or the slot gets airflow, that may help. If you are fitting it into a laptop or small-form-factor case, the lack of published power data makes battery life and thermal behaviour harder to predict.

The drive comes with Crucial Storage Executive, which shows drive health, wipes drives and updates firmware. Acronis True Image for Crucial is also included. The health readout matters more on a drive with a 440 TBW rating, since it lets you keep an eye on wear.

According to a search snippet of Crucial's P310 support page, there are "No firmware updates at this time". That means there is no update history to judge yet, good or bad. The tooling to apply updates exists if Crucial releases any.

The P310 2TB pairs rated speeds of 7,100 MB/s read and 6,000 MB/s write with DRAM-less QLC hardware and a low 440 TBW rating. It makes sense as a large drive for a gaming PC or general desktop, where most of the data is written once and read many times. The five-year warranty and bundled software are sensible extras.

It makes less sense anywhere writes pile up. Homelab VM storage, databases, NAS caching or regular large file transfers will eat into the endurance rating. Owner reports from other variants also point to slower sustained writes. Power and thermal data is thin, so mobile buyers have little to go on. Buy it for read-heavy use and capacity. Look elsewhere if write endurance is a priority.
